Hi all,
I wonder if there is an easy way to multiply, for example, the value of a branch in the TTree::Draw method, without change the original value of the branch?
I want to do something like this:
I have a tree with the branches var and time:
float b = 2;
Tree->Draw(“var:time*b”);
When I multiply the branch time by a number 2, it works. But it doesn’t work when I multiply by a variable b.
Thank you.
